Bluetooth headed for smaller spaces

Cambridge Silicon Radio introduces software aimed at pushing the wireless technology into small, portable devices like mobile phones and handheld computers.

The United Kingdom's Cambridge Silicon Radio on Wednesday introduced Bluetooth software aimed at pushing the wireless technology into small, portable devices like mobile phones and handheld computers.

The BlueCore Host Software reduces the memory and processing power requirements for adding Bluetooth to a device, which should make the option more attractive to hardware manufacturers.

Bluetooth is a short-range radio technology for connecting peripherals, devices and PCs to one another without cables. It is becoming available now in some mobile phone handsets and PDAs (personal digital assistants), but analysts say it will only become really valuable when it becomes ubiquitous in all sorts of devices.

The BlueCore Host Software is expected to ease the job of the device's main hardware, such as its processor, by off-loading much of the hardware's task of running Bluetooth's software stack. Because the BlueCore Host Software unloads much of the processing work onto the company's BlueCore Bluetooth chip, it will save the device's battery life and help performance by reducing demand on its processor and memory, the company said.
